Strength Training Calories

gracelw3d

Hi! I am new to mfp and excited by the great looking site and the tools! One things I'm curious about is why there are no calories attached to strength training. I work out with a personal trainer and my cardio really gets up there (at least based on the huffing and puffing I do LOL).

Also, are the calories based on your weight (i.e. the more you weight the more you burn)

Thanks!
